Star War Simulation: Projectile Physics in VB6
Educational Purpose
This simulation game demonstrates the fundamental principles of projectile motion in physics. By adjusting launch angles and velocities, users can explore how these variables affect a missile's trajectory, range, and height.
The game provides excellent training for students to develop their estimation skills and understanding of physics concepts applied in real-world scenarios.
Projectile Physics Principles
Trajectory Calculation
The missile follows a parabolic trajectory calculated using physics formulas:
Horizontal displacement = v cos A * t
Where:
- v = launch velocity
- A = launch angle
- g = gravitational acceleration (9.8 m/s²)
- t = time
Optimal Launch Angle
The maximum range is achieved at a 45-degree launch angle. This principle is visually demonstrated in the simulation as players adjust angles to hit targets.
Real-world Applications
These physics principles have practical applications in:
Implementation in VB6
The simulation uses Visual Basic 6's object positioning system combined with physics calculations:
' Calculate missile position using projectile formulas v = Val(Text1.Text) ' Get velocity from input a = Val(Text2.Text) ' Get angle from input t = t + 1 ' Increment time ' Convert angle to radians radians = a * 3.141592654 / 180 ' Calculate vertical and horizontal displacement y = v * Sin(radians) * t - 4.9 * (t ^ 2) x = v * Cos(radians) * t ' Move the missile image Image1.Move Image1.Left + x, Image1.Top - y
Dynamic Game Elements
The game includes several dynamic features:
- Randomized Targets: Objects appear at random positions for each new game
- Multiple Backgrounds: Different backgrounds load randomly at startup
- Collision Detection: The program checks when the missile hits a target
- Score Tracking: Players earn points for successful hits
